Holiday-makers jetting off today may have to wait a little longer to get their journeys underway, as French Air Traffic Controllers are on strike again.
This is the thirteenth strike in fourteen weeks and is affecting flights into and out of France, as well as those that fly over French Airspace.
Ryanair says 18,000 of its customers are facing cancellations and over 100,000 will face severe delays.
It is calling on the EU to allow flights to pass over France during the strikes and to require unions to participate in binding arbitration to bring an end to the matter.
Ryanair's Kenny Jacobs, is also encouraging passengers to show the EU how they feel: “We would call on all our customers in Ireland and Europe to sign a petition which we have set up which is called ‘Keep Europe’s skies open’.
“And we are going to bring one million signatures to Brussels to finally to get the EU commission to do something.”
